FIELD: nanotechnology.

SUBSTANCE: invention relates to the field of nanotechnology and can be used to obtain monodisperse nanostructures, in particular, dispersed single nanoparticles from bundles and tangled agglomerates of nanoparticles on the surface of a binder base. The method includes the supply of bulk nanomaterial to the nanoparticle dispersion unit 4 in a compressed gas flow, which ensures the primary movement of the nanomaterial through the bypass 5, the passage of the resulting dispersion into the first cyclone separator 13 to separate the dispersed single particles from the remaining aggregated and agglomerated ones due to the effect of gravity on the particles of the nanomaterial and centrifugal forces, sedimentation of aggregated and agglomerated particles with their subsequent transfer back to the mentioned dispersion unit 4 to repeat the dispersion cycle and subsequent separation of single nanoparticles from the remaining aggregated and agglomerated particles, selection of dispersed single nanoparticles separated by an upward gas flow from the first cyclone separator 13 into the forming reaction zone the central channel 31 of the deposition block of 16 individual particles of nanomaterial on the surface of the binder base, the supply of the formed composite material to the second cyclone separator 24, the separation of the formed of the selected composite material from individual particles selected by an ascending gas flow that did not have time to fix on the surface of the binder base, with their further transfer back to the reaction zone of the deposition unit 16 to repeat the cycle of deposition of individual nanomaterial particles on the surface of the binder base, the extraction of the target product through the lower nozzle 25 and the storage tank 26 of the second cyclone separator 24. An installation that implements this method is shown.

EFFECT: due to the closed cycle of separation of single nanoparticles, which excludes the formation of waste in the form of agglomerated and aggregated particles, the technological process is simplified, and at the same time the quality of the target product is increased due to the cyclic effect on the nanomaterial at the stages of dispersion and further formation of finished nanostructures for fixing the dispersed particles on the surface of the binder material in order to prevent their re-agglomeration.
